Estou tentando utilizar o seguinte comando: sudo apt update && sudo apt install build-essential software-properties-common -y && sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && sudo apt update && sudo apt install gcc-snapshot -y && sudo apt update && sudo apt install git libc6-dev gcc-6 g++-6 libc6-dev:i386 g++-6-multilib gdb -y && git clone --recursive
https://github.com/nullifiedcat/cathook && cd cathook && make -j4
e essa é a saída quando digito egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/* no terminal:
egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*

e essa quando digito lsb_release -rd:
Description: Ubuntu 16.04.2 LTS
Release: 16.04
pelo que entendi eu devo criar um arquivo dentro da apt.conf.d, com o nome de 99porteiraaberta e colocar APT::Get::AllowUnauthenticated "true"; nele, e no caso quando eu terminar de instalar os pacotes eu posso fechar substituindo true por false?
